# Minsud Announces Maiden Mineral Resource Estimate for the Chinchillones Complex at the Chita Valley Project Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/minsud-announces-maiden-mineral-resource-estimate-for-the-chinchillones-complex--f3eacb5c-a36f-446f-a956-cd5b5bdcce6c Original source: https://money.tmx.com/en/quote/MSR/news/7281158224540191/minsud-announces-maiden-mineral-resource-estimate-for-the-chinchillones-complex- Publisher: tmx Original announcement: 2025-01-17T22:27:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Minsud Resources Corp. - Ticker: MSR - Exchange: TSX - Region: San Juan Province, Argentina - Primary commodity: Copper - Secondary commodities: Gold, Silver, Molybdenum, Zinc - Document categories: Resource update, Metallurgy - Extracted: 2026-08-25 23:14:49 UTC Narrative sentiment: 0.40 · Bullish ## Minestarters Atlas summary Minsud Resources Corp. has announced a maiden Mineral Resource Estimate for the Chinchillones Complex at the Chita Valley Project in Argentina, totaling 761Mt \(188Mt Indicated, 573Mt Inferred\). The resource is suitable for open-pit mining and flotation, though metallurgical testing highlighted arsenic and zinc as potential smelter penalty elements. Reasoning: The announcement of a maiden resource of 761Mt with significant copper, gold, and silver content is highly material, though high arsenic penalties and a large inferred component introduce technical risk. - Positive factor: Maiden resource estimate established - Positive factor: Significant tonnage \(761Mt total\) - Positive factor: Multiple commodities contributing to NSR - Positive factor: QP sign-off provided - Positive factor: QA/QC protocols disclosed - Negative factor: High arsenic content in concentrates - Negative factor: High zinc levels in certain domains - Negative factor: Significant portion of resource is Inferred \(75%\) - Negative factor: Complex mineralogy requires mineralogy-based NSR calculations Facts used in scoring: 29 ## Classification and evidence **Maiden Resource** Polarity: neutral Definition: First formal MRE for the project — establishes baseline but typically exploration-stage with high Inferred component. Why it applies: The company announced its first formal Mineral Resource Estimate for the Chinchillones Complex. Evidence · text > completion of a maiden, pit-constrained Mineral Resource Estimate **QP/CP Signed** Polarity: positive Definition: Qualified Person \(QP\) or Competent Person \(CP\) named and signed off — a member of a recognized professional association \(e.g., AusIMM, SME, AIG, P.Geo\) with relevant experience. Why it applies: Mr. Mike Job, a Qualified Person under NI 43-101, oversaw the estimation. Evidence · text > As a Qualified Person \(QP\) under NI 43-101 standards, Mr. Job oversaw all aspects **NI 43-101 Compliant** Polarity: positive Definition: Resource estimate prepared in compliance with NI 43-101 \(Canada\) — high reporting standard. Why it applies: The resource is reported in compliance with NI 43-101 standards. Evidence · text > It is reported in compliance with the requirements of the Canadian Securities Administrators' National Instrument 43-101 \(NI 43-101\). **Deleterious Elements Present** Polarity: negative Story-specific tag Definition: Penalty elements \(arsenic, antimony, etc.\) or refractory concerns noted in the release. Why it applies: Metallurgical testing revealed significant challenges with arsenic \(As\) content in concentrates. Evidence · text > Results showed significant challenges with arsenic \(As\) content in concentrates \(averaging 7%\) ## Extracted facts Stored fact records: 29.
